Naeem,
you cannot assume that OpenMP is available as that is an optional capability,
so make sure you make the inclusion of omp.h optional. Please read section
1.2.1.1 OpenMP support of the Writing R Extensions manual:
https://cran.r-project.org/doc/manuals/r-release/R-exts.html#OpenMP-support
Cheers,
Simon
